a citizen of the United States, and resident of East Cleveland, in the countyof Cuyahoga and Stateof Ohio, have invented cerf' tain new and useful Improvements'in ,Auto-i matic Devices for Coating and Covering Fibrous'Elements with a Fluid and SolidAdhesive,'.of which I hereby declare the vfollowing to be a' full, clear, ,and exact description, such as will enable others skilledin 'the lart to which it appertains to make and 4use the same.

The vobjects of the invention'are to provide mechanism). for incorporating a layer or stripsfof rsolid rubber',- orother adhesive,

Within the bodyof as' laminated,` flattened,

through twoor more of which are conduct-` edvv strlps orbands of unvulcanized, solid adhesive. The Aseries of. fibrous elements from the winding head are, some of them,

wound on the central tubular mandrel, -and Wound around the entire group of mandrels as a unit. Thesolld adheslves are separated other series .of the fibrous elements arev from theliquid adhesive inthe coating chamber by the inclosing mandrels While the -fibrous. elenlfents are being coated With fluid adhesive,jandtheyemerge from the outer extremities of the mandrels and areso posi- .tioned-"s to be immediately interposed between theg'roups` or series ohrous ele- `ments rasthe band is'being. pulled olli-from i themandrelsc Thesolid adhesive in the centralmandrel is encircled by series of fibrous elements and the outer strips of adhesii'feare alsoencircled by series of fibrous elements, and together v with the librouselements are pulled oil' fromv the mandrels by a suitable pulling device.

The rinvention is scribed, illustrated in the accompanying claims.

hereinafter 'furtherl de` drawings andspecilically pointed out in the In the accompanying drawings Figure is a longitudinal central sectionof the inclo's'ed when vor' ierating the machine, t rough which Vthe'irlandrels passend uponwhich the-br'ous' i elementsare separated toexpose thenilto the liquidcoating; Fig.p 4 is a transverse sec- :f'ff `-tl 1` a same'on' line a-a Fig, iszan larged plan view of a portion of; a andrei through which onegof the end ofthe central'mandrel showing two tubular mandrels for'applying solid adhesive bands to the fibrous elementsupon the mandrel; Fig. 8 is va'transverse section, eny larged, on line c," c, Fig. 3, of the mandrels where they are inclosed in the coating cham ber; Fig. 9 is a similar section online b, b Fig. 7 after they emerge from the rubber chamber.

In these views the Vvconstruction of the reels A, A, A2 and Aa which rotate about a hollow mandrel B, and are supplied with spindles C', C', CQC', upon which are mounted spools, c', c', c', c', upon which the arn ele.- ments D, D, D,` D, are stored, has een described in my co-pending applications. From these spools the yarn elements are 'guided to the mandrelsv byA meansl of guide' rollers E, E, E, E, and guiderings E', E',

VE', E asshown in Figs. l and 2, and as the reels and ,guides rotate, are wound upon the mandrels in series of arallel rows, spaced apart to form diamond) one series crosses the other. Four series compriseA a fabric band of two layers or laminations, and each series is positioned upon the mandrel to coverthe, spaces ofthe parallel series below. After the first series and the second' series, which crosses the first series at a predetermined angle, have been wound around the central hollow mandrel B,'the third and fourth series of yarn .ele-

ments are wound upon the outer mandrels vwhich comprise flattened tubes F, F, and the central mandrel `B- asa unit. Bands G, G, of solid adhesive pass through the tubesA F, F, which are positioned one upon each side of the central mandrel. This mandrel is also preferably hollow' and -flat tened and a band of solid adhesive G",pas'ses therethrough. y

The bands of adhesive are preferably stored in suitable rece tacles I, I, and are so coiled as to be Vreadlly drawn therefrom. They are preferably coated with a practically non-adhesive powder, which prevents the folds from cohering, and can be vulcanized into the adhesive afterward without any material injury to the adhesive. The outer bands of solid adhesive l'are `led through guiding channels or tubes J, J, and these guides communicate with the flattened tubular mandrels F, F.Y The outer mandrels F, F, are positioned above and below the mandrel B within the coating chamber as shown in Figs. 3, 4, and 8, and outside of the outer extremity of the coating chamber K they are curved about the edges of the.

ments '(1, l, Fig. 7) are laid upon the inner4 band GrA of adhesive, and the two -outer seshaped openings as H ries (2,22, Fig". 7 lare laid upon the outer bands G, G,'-of a hesive; y `The central mandrel, is designed to separate the .fibrous elements on allthe ma'ndrels as the elements pass throughfthe coating -chamber K, and to accomplish vthis result, the central mandrel is'extended laterally at b, b, and openingsb,` bf, are ,made'therein throu h which theliquid .adhesive will flow so as tol coat each fiber of the fibrous elements therewith, beforethe bands of` adhesive are interposed among the fibrous elements, thus separating the fibrous elements from contact with each otherand incorporating a large body of solid adhesive within 'the band.

Au improvement is made in the coating chamberv K, to prevent the piling up of the adhesive at the, forward end, and equalizing the pressure throughout the chamber. This comprises the false'bottom K providing a conduit communicating with the extremities of the chamber K at K2, K, so that the adhesive vwill pass therethrough when the pressure becomes greater at the forward end4 of e thg chamber and will returnto the other en 1 The fibrous elements are coated in the coating chamber and the bands of solid adhesve are interposed 4therewith as the fibrous 1 elements are `drawn ofl from the `mandrel by Vthe pulling device. The fabric band D" is wound upon a spool S, upon whichit is stored, and between the coils is interposed a band of non-adhesive material such as Holland cloth or lno n-adhesive metal ribbon T.-

The lpulling device isshofwn to comprise rollers AX, X, X,fwhich slightly` and progressively increaseindiameter, soas to place a slight, tension. upon 'the band :to Hatten and straighten the same. i1 i To eliminator any undesirable moisture from the yibrous elements which might pre two strips of solid adhesive in thefabric.

',band, and employing two hollow' guiding members therefor, one' band ofsolid adhesive may be used which may be wide enough to form a single envelopinA layer around the first seriesof fibrous."` e ements woundY upon the central-mandrel and may be guided by a tubular member y:formed to practically encircle the said ycentral mandrel without departing from the spirit of the invention or the scope of the claims.
